Comparative Assessment of Inclisiran on Top of Standard of Care Versus Standard of Care Alone for LDL-C Evaluation in Acute Coronary Syndrome Patients in Saudi Arabia

Comparative, Randomized, Multicenter, Followed by an Open Label Extension Trial in Patients With a Recent Acute Coronary Syndrome Evaluating the Early Inclusion of Inclisiran Into Standard of Care Versus Standard of Care Alone in Kingdom of Saudi Arabia

This study aims to evaluate the effectiveness and safety of implementing a systematic augmented low-density lipoprotein cholesterol (LDL-C) management care pathway initiated in hospitals for patients with Acute Coronary Syndrome. This pathway includes treatment with inclisiran on top of the standard of care (SOC), which consists of statins with or without ezetimibe, compared to a high-intensity SOC regimen alone (statins +/- ezetimibe).

Study Overview

• Status: Not yet recruiting
• Conditions: Acute Coronary Syndrome
• Intervention / Treatment: Drug: inclisiran; Drug: SOC

Detailed Description

This multi-center phase IV study adopted a two-phase design. The first phase (Day 1 to Day 90) is an open-label, randomized, comparative parallel-group design comparing an LDL-C management strategy that includes inclisiran with SOC versus SOC alone. The second phase is an open-label extension design (Day 90 to Day 210). After the EOI visit, the participants from phase 2 will be invited to participate in a 1-year long-term observational phase to assess medication adherence and satisfaction.

Participants eligible for inclusion in this study must meet all of the following criteria:

1. Males and females ≥18 years of age.
2. Recent ACS (in-patient/out-patient) within 7 days of index admission, as per 2023 ESC guidelines for the management of acute coronary syndrome
3. Serum LDL-C ≥1.8 mmol/L (≥70 mg/dL) or non-HDL ≥100 mg/dL at screening for participants who were receiving SOC [including lipid lowering therapy and/or ezetimibe] prior enrollment.
4. Serum LDL-C ≥2.6 mmol/L (≥100 mg/dL) or non-HDL ≥124 mg/dL at screening for participants who were SOC treatment naïve prior enrollment.
5. Fasting triglycerides <4.52 mmol/L (<400 mg/dL) at screening.
6. Estimated glomerular filtration rate (eGFR) >30 mL/min at screening.
7. Participants must be willing and able to give informed consent before initiation of any study related procedures and willing to comply with all required study procedures.

Exclusion Criteria:

Participants meeting any of the following criteria are not eligible for inclusion in this study:

1. Any uncontrolled or serious disease, or any medical or surgical condition, that may either interfere with participation in the clinical study and/or put the participant at significant risk (according to investigator's [or delegate] judgment) if he/she participates in the clinical study.
2. An underlying known disease, or surgical, physical, or medical condition that, in the opinion of the investigator (or delegate) might interfere with interpretation of the clinical study results.
3. New York Heart Association (NYHA) class IIIb or IV heart failure or last known left ventricular ejection fraction <25%.
4. Significant cardiac arrhythmia within 3 months prior to randomization that is not controlled by medication or via ablation at the time of screening.
5. Uncontrolled severe hypertension: systolic blood pressure >180 mmHg or diastolic blood pressure >110 mmHg prior to randomization (assessed at screening visit) despite antihypertensive therapy.
6. Homozygous familial hypercholesterolemia (HoFH) defined as LDL-C ≥ 12 mmol/L.

Women of childbearing potential, defined as all women physiologically capable of becoming pregnant from menarche until becoming post-menopausal, unless they have had surgical bilateral oophorectomy (with or without hysterectomy), total hysterectomy or bilateral salpingectomy at least six weeks before taking study treatment. In the case of oophorectomy alone, the reproductive status of the woman needs to have been confirmed by follow-up hormone level assessment.

11. Breastfeeding women.
12. Treatment with other investigational products or devices within 30 days or five half-lives of the screening visit, whichever is longer.
13. History of hypersensitivity to any of the study treatments or its excipients, or to drugs of similar chemical classes (statins, ezetimibe, and inclisiran).
14. Planned use of other investigational products or devices during the course of the study.

15. Any condition that, according to the investigator, could interfere with the conduct of the study, such as but not limited to:

    1. Participants who are unable to communicate or to cooperate with the investigator.
    2. Unable to understand the protocol requirements, instructions and study-related restrictions, the nature, scope, and possible consequences of the study (including participants whose cooperation is doubtful due to drug abuse or alcohol dependency).
    3. Unlikely to comply with the protocol requirements, instructions, and study-related restrictions (e.g., uncooperative attitude, inability to return for follow-up visits, and improbability of completing the study).
    4. Persons directly involved in the conduct of the study.
16. Treatment with monoclonal antibodies directed towards PCSK9 or inclisiran within 60 days of screening or planned use of it as SOC during next 210 days.
17. Active liver disease defined as any known current infectious, neoplastic, or metabolic pathology of the liver or (ii) alanine aminotransferase (ALT) elevation >3x ULN, aspartate aminotransferase (AST) elevation >3x ULN, or total bilirubin elevation >2x ULN (except patients with Gilbert's syndrome) at screening confirmed by a repeat measurement at least one week apart.
18. Uncontrolled Diabetes Mellitus (DM) defined as HbA1c > 9%.
